Attached example demonstrates SPI data transfer between SPI0 and SPI1 in DMA mode for ADSP-SC584. You need expansion interface and connect in P1A connector of Ezkit as below:
TX P1A --> RX P1A
SPI0 CLK PC_09 (Pin 82) --> SPI1 CLK PE_13 (Pin 113)
SPI0 MOSI PC_11 (Pin 84) --> SPI1 MOSI PE_15 (Pin 114)
SPI0 MISO PC_10 (Pin 83) --> SPI1 MISO PE_14 (Pin 8)
SPI0 SEL1 PC_07 (Pin 39) --> SPI1 CS PE_11 (Pin 20)SC584_SPI_Core0.zip
